We all know Ally Brooke is an amazing singer, but how good is she at remembering lyrics from throwback classics? We tested the former Fifth Harmony singer's knowledge of 2000s-era bangers, like Ciara's "1, 2, Step," Beyoncé's "Crazy in Love," and more! Honestly I'm still floored by her Shakira impression. How many of these songs were your jam 10 years ago?
